Do not use onchange event handlers on select elements.
Use selections should be made using the enter key.
Move focus to the selection box and use the keyboard to move the focus between options, check to make sure the focus changes are not causing the context to change (i.e. focus movig to a new window or focus moving from the current option in the select box).
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
